Application filed September 23, 1919. Serial No. 325,792.

To all whom it may concern:

Be it known that I, ADRIAN J. CHAVANNES, a citizen of the United States, and a resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Printers Drying-Cabinet, of which the following is a specification.

The object of my invention is to provide a printers drying cabinet of simple, durable and inexpensive construction.

A further object of my invention is to provide a printers drying cabinet which will enable printers to dry their job printing in a short time at a minimum expense.

A further object is to provide a device whereby printed matter may be hardened quickly to thereby cause a more perfect finish and at the same time make itv possible to quickly and easily complete a job of printm it further object is to provide a cabinet having a heating member therein and tiers of paper stock supporting racks so arranged that a circulation of heated air may be passed around said supporting racks,'thereby drying paper having printed matter thereon in a very short time.

A further object is to provide a cabinet whereby dampness and electricity may be removed from paper stock about to be used for printing, thereby making the handling of the paper stock very easy, and at the same time placing the paper in such a condition that a job of printing may be done while the paper stock is in its prime condition.

Still a further object is to provide a cabinet for drying printedwork which is provided with tiers of supporting racks which may be selectively spaced in said cabinet to accommodate various sizes of bundles of paper stock, the supporting racks being removable from said cabinet so that thepapeir may be placed upon said racks and then be placed into the drying cabinet for drying.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, in which:

Figure 1 shows a perspective view of my improved drying cabinet showing the doors thereof in open position.

Fig. 2 shows a perspective view of one of prises a top 10 and a bottom 11 with the side wall members 12 and aback 13. Hinged to the front of the cabinet A are the door members 14 which are provided with suitable means 15,so that they may be locked and held in that position.

The cabinet is mounted on the legs 16. The top 10 and bottom -11 are provided with openings 17 and 18, the purpose of which will be hereinafter more fully set forth.

Supported on the bottom or base 11 is a bracket 19, which supports the heating member 20. The heating member 20 is preferably an ordinary gas pipe having a plurality of openings therein, so that gas which may be passed into the heating member 20may be lighted, thereby causing heat to be radiated from said member.

The heating member 20 extends through the wall 12 of the cabinet and is provided with a cut-off 21.

By using the cut-off 21 I am able to regulate the amount of gas which will be permitted into the heating member, thereby regulating the amount of heat within the cabinet.

Spaced somewhat above the heating member 20 is a screen partition member Bwhich comprises a rectangular frame 22 and the screen portion 23.

' The frame 22 is provided on the sides adjacent to the sides 12 of the cabinet with downwardly extending flanges 24. The flanges 24; have openings 25 therein, so that the device may be detachably fixed to the cabinet.

Spaced parallel guide members 26 are fixed to the sides 12 of the cabinet. The guides 26 are designed to receive and sup port the paper. supporting racks C.

The paper supporting racks C comprise end members 27 which are fastened together by spaced parallel slats 28.

The end-members 27 of the paper supporting racks are adapted to rest upon the guides 26.

The paper supporting racks may be placed at various intervals in the cabinet, so that spaces of various'sizes may be had for'accommodating paper stock of various thicknesses.

. net. After the paper is placed in the cabinet, the heating member is then put in operation, and the doors 14 of the cabinet are closed.

The heat from the heating member 20 will pass upwardly through the screen 23 and circulate through the spaces between the slats 28 of the rack C, and around the paper stock which is placed upon the racks and escape through the openings 17 in the top of the cabinet.

Cold air will be taken in through the openings 18 in the bottom and will pass upwardly around the heated member, thereby heating the air in its circulation, so that any paper stock which is in the cabinet may be quickly dried.

It is very desirable to be able to dry the printed matter quickly after it is printed,

because when the ink is yet fresh and it is dried quickly, a more perfect finish is obtained than were the printed matter permitted to dry by the ordinary method.

In this connection it might be stated that a job of printed matter may be quickly gotten out by the use of my improved printefis drying cabinet without any great amount of expense.

The partition member B is providedfor preventing any of the paper stock, which is placed in the cabinet on the racks, from coming in contact with the: heating member 20.

Some of the paper stock might'be accidentally thrown off the racks and were this partition member not provided a fire would result.

The object of the partition member is to relieve this danger.

My printers cabinet can also be used advantageously for drying paper stock before the printing is done. 7

It is well known that electricity is formed in the paper from dampness, and it is very hard to obtain a smooth finished printing job when the paper is damp.

In order to obtain a perfect finished printing ob it is necessary that the paper be in a certain condition; that is, absolutely dry.

fore use and leaving the paper'in the cabinet for. a few minutes, all the dampness and electricity in the paper will be removedtherefrom, so that I can then proceed with ,the printing when the paper is in the prime placing the stock in my cabinet just be 7 cloudy days when it is almost impossible to 7 print the other side of the sheetwithout waiting four or five days. 7

In some printing shops where a rush job is performed and it is impossiblelto wait the four or five hours, the printerwill print the other side any way and turn out a smeary job of printing; V r

By the use of my cabinet after one side of the sheet is printed and placed in a cabinet, then in a very short time I am able to print the other side of the sheet, and at the same time have the job completed in a very short time, and better than could be'obtained otherwise.

Some changes may be made in the construction arrangement and combination .of the parts of my device without departing from the essential features and purposes of 5 V 100' my invention, and it is my intention to cover by my cla1m any 'modlfied forms of structure or use of mechanical equivalents which bundles of paper of various thicknesses may I be accommodated, said racks including slats may pass through said rack, a'heating member near the bottom of said cabinet, means for regulating the amount of heat permitted to clrculate through said cabinet, a screenpartition placed in said cabinet above-said heating member, and below said paper sup porting racks, thereby preventing any paper from accidentally coming in contact with said heating member, said'cabinet being provided with openings in its top and bottom for permitting air to pass in and pass out thereby forming a circulation which,

when heated, will quickly dry the'paper' stock on said racks.
